Feedback on possible extra language features

[Stephen Colebourne]

Following the hg commits, there seem to be three possible additional
language tweaks around lambdas. Here is some feedback from me and my
colleagues.

1) Static methods on interfaces
Collesgaues: Viewed positively, although will take a while to get used
to the new design possibilities
Me: For JSR-310, we have two classes waiting to disappear once this
feature is confirmed.

2) Private methods on interfaces
Colleagues: Less certainty as to how this would get used, but expect
it be useful in making interfaces more trait-like.
Me: No immediate need to use this in JSR-310

3) Package scope modifier on classes and interfaces
Colleagues: About **** time. Strong desire to use it everywhere and
eliminate default scope and /* package */ "comment modifiers".
Me: Want to ensure that coding standards across the JDK are changed so
that the default scope is not used anywhere - classes or interfaces.

Hope this helps
Stephen
